Abstract
A system for estimating the modulation index and frequency offset of a CPM signal. An estimator filters the received signal and utilizes a training sequence to determine the modulation index and frequency offset of the CPM signal. The estimator can also include a post-processing step to eliminate all or part of a bias that might be created by the estimator.
